Abstract

Between January and June 2004, a total of 200 nondepurated mussel samples of the Galician coast (northwest Spain) were examined for Giardia cysts with a direct immunofluorescence antibody test. Giardia cysts were found in mussels from all of the estuaries studied, with an overall rate of contamination of 41.5%. There was relation between the presence of Giardia cysts, the microbiological contamination (expressed as most probable number of Escherichia coli) detected in the samples, and the harvesting area. This is the first work that describes the presence of Giardia cysts in mussels (Mytilus galloprovincialis) destined for human consumption.

摘要

2004 年 1 月至 6 月期间，对加利西亚海岸（西班牙西北部）的 200 个未经净化的贻贝样本进行了检测，以发现贾第虫包囊，采用的方法是直接免疫荧光抗体试验。在所研究的所有河口都发现了贻贝中的贾第虫包囊，污染总率为 41.5%。贾第虫包囊的存在与样本中检测到的微生物污染（以大肠杆菌最可能数表示）以及捕捞区之间存在关系。这是第一份描述人类食用贻贝（Mytilus galloprovincialis）中存在贾第虫包囊的报告。
